I've found HN pretty divided when it comes topics like energy/climate/electric vehicles, immigration and foreign policy.
Before I used to feel bad, now I somewhat expect to be downvoted bringing up anything that doesn't fit someone's worldview.
I lived a decade in Seattle, WA which is a strong blue/liberal state as it goes. Sometimes pretty extreme. Now I am in Florida which is now a solid red state since Trump. It's interesting to see how the thought bubbles and world views have formed.
